The Planetary Habitability Laboratory (PHL) is a research and education laboratory dedicated to studies of the habitability of Earth, the Solar System, and exoplanets. Check the projects link for more details about the scientific projects. There are also links to scientific and educational materials, data and software tools related to planetary science and astrobiology that might be of interest to scientists, students, and the general public. The PHL is managed by the University of Puerto Rico at Arecibo.
